Successful Late Recruitment of the Occluded Left Main Coronary Artery After Initial Arterial Switch Operation

We describe a surgical technique for late recruitment of the proximally occluded left main coronary artery (LMCA) after initial arterial switch operation, which had been complicated by severe left ventricular dysfunction. This technique allowed for LMCA recanalization, using the patent conal artery branching off the LMCA close to the ostium. It is particularly useful in small children, where surgical options for coronary arteries are limited and associated with a high risk of restenosis. It was successfully used in a two-month-old boy with successful revascularization confirmed by angiography
